Although Kepler completed its primary mission to determine the fraction of stars that have planets in 2013, it is continuing the search, using a more limited survey mode, under the new name K2. The K2 Data Search Service provides the main catalog for all K2 data. http://archive.stsci.edu/kepler/ Archive Research 2 http://archive.stsci.edu/k2/data_search/search.php? GET 180 false K2 Optical
